Detailed Explanation
Nhưng (but) is a primary coordinating conjunction used to connect two clauses or phrases that express a contrast or opposition. It functions very similarly to 'but' in English, linking ideas within a single sentence. It's versatile and can be used in both spoken and written contexts, making it the more common choice for everyday conversations and less formal writing. When using nhưng, the contrast is often more direct and immediate, often addressing a potential counter-argument or qualification of the first clause.
Tuy nhiên (however/nevertheless), derived from Hán-Việt, functions as an adverbial phrase or a discourse marker. It connects a sentence or an idea to a previous sentence or broader context, signaling a contrast or concession. Tuy nhiên implies a stronger shift or a more significant counterpoint than nhưng. It is generally more formal and frequently appears in written documents, academic papers, official reports, or more formal speeches. When tuy nhiên introduces a new sentence or clause, it is almost always followed by a comma.
Think of it this way: nhưng links two parts of the same thought or sentence, while tuy nhiên links a new thought or sentence that contrasts with the previous thought or statement. This distinction in scope and formality is crucial for B2 learners to master.

Common Patterns
- "Tuy... nhưng..." (Although/While... but...): This is a common correlative conjunction structure where nhưng is integral and cannot be replaced by tuy nhiên.
Tuy trời mưa, nhưng chúng tôi vẫn đi chơi.
Although it was raining, we still went out.
Tuy nghèo, nhưng anh ấy rất tốt bụng.
Although poor, he is very kind-hearted.
- Starting a formal sentence/paragraph: Tuy nhiên is preferred when you introduce a contrasting idea at the beginning of a formal sentence or a new paragraph, often separated by a comma. It signals a shift in topic or a major counterpoint.
Báo cáo cho thấy doanh số tăng trưởng. Tuy nhiên, lợi nhuận ròng lại giảm.
The report shows sales growth. However, net profit decreased.
- After an affirmative statement that is then qualified: Tuy nhiên works well to qualify a broad statement or introduce an exception or limitation after a general assertion.

The government has issued many support policies. However, implementation still faces many challenges.
Common Mistakes
Mistake 1 — Using tuy nhiên too informally or within a simple clause
Learners sometimes overuse tuy nhiên in situations where nhưng would be more natural and appropriate for everyday conversation or simple sentence structures.
❌ Tôi muốn ăn phở, tuy nhiên tôi không có tiền.
✅ Tôi muốn ăn phở, nhưng tôi không có tiền.
In this simple, direct contrast within one thought, nhưng is much more natural and common. Tuy nhiên makes the sentence sound overly formal or a bit clunky for casual conversation, as if you're writing an essay about your desire for phở.
Mistake 2 — Starting a new formal sentence with nhưng
While nhưng can occasionally start a sentence in very informal spoken contexts for emphasis, it's generally considered less formal and grammatically incorrect to use it at the beginning of a new sentence in formal writing where tuy nhiên is expected.
❌ Tình hình kinh tế đang khó khăn. Nhưng chính phủ vẫn lạc quan.
✅ Tình hình kinh tế đang khó khăn. Tuy nhiên, chính phủ vẫn lạc quan.
When connecting two distinct sentences with a contrasting idea in a more formal context (like a report or official statement), tuy nhiên is the appropriate choice. Nhưng should generally not start a new sentence in formal writing.
Mistake 3 — Forgetting the comma after tuy nhiên
As an adverbial phrase introducing a contrasting clause or sentence, tuy nhiên almost always requires a comma immediately after it, especially when it begins a sentence or an independent clause.
❌ Anh ấy đã cố gắng. Tuy nhiên anh ấy thất bại.
✅ Anh ấy đã cố gắng. Tuy nhiên, anh ấy thất bại.
When tuy nhiên introduces a clause or sentence, it is almost always followed by a comma to mark its role as an introductory adverbial phrase. This is a common punctuation rule in Vietnamese formal writing.
